Big difference between theory & experience! I will go with experience every time. Just so everybody knows two strokes were still lean spitting until DFI came along. Maybe even worse as fuel mixtures got leaner for fuel economy efforts. First outboard oil injection (1984) brought about a Flame Arrestor Kit #174624. Tied right onto the crankcase where the fuel pump hose goes to drive the fuel pump. Prevented the diaphragm on the air pump being burned from crankcase explosions (lean spits).
The first attempts were just steel wool stuffed in the braided hose to squelch the fire. Later they developed a valve (pulse limiter) that stopped the measured 75 lb. pressure spikes that would blow the air motor apart in the pump. Some serious energy in the crankcase!
